Ubuntu – How to create a bootable usb of Ubuntu from a Lubuntu system

This is just to mention that Canonical now recommends the Rufus USB Installer. (I haven't used it myself.)

Instructions (copied from the Canonical instructions):

1. Open Rufus and select your USB stick in the 'Device' dropdown
2. Click the CD Rom icon next to the 'FreeDOS' dropdown, then find your downloaded Ubuntu ISO and click 'Open'
3. Click 'Yes' when it asks to download Syslinux software
4. Click 'OK' to write in ISO Image mode
5. Confirm that your USB stick is selected and then 'OK' to continue
6. When it is finished, just restart your computer and start using Ubuntu, or you can install Ubuntu

To install Startup Disk Creator, run the following in the terminal:

sudo apt-get install usb-creator-gtk
